I'll help you figure this out, but I won't do it for you.

1. Look up the chemical formula for Copper Carbonate Hydroxide Hydrate. Hint: There is more than one hydroxide. There's only hydrate (water).
2. Look up or figure out what the decomposition products are. Hint: Water comes off and the carbonate decomposes.
3. Write the equation with a double-headed arrow between the copper carbonate hydroxide hydrate and the products.
4. Balance the equation.

Show me what you've come up with and I'll help you further.

I have to write the chemicle equation for sodium phosphate + potassium chloride. I have Na3PO4 + KCl= 3NaCl + KPO4
3Na+ + PO4(-2) + K+ +3Cl= 3Na+ 3Cl- +KPO4
PO4-2 + K= KPO4
Is this the right answer.

No. Phosphate is PO_4^{-3} Potassium is K^+ Sodium is Na^+ and chloride is Cl^-

This is the balanced equation:

Na_3PO_4 + 3KCl= 3NaCl + K_3PO_4

Of course, in water solution, you'll get simply the ions:

Na_3PO_4 + 3KCl= 3Na^+ + 3Cl^- + 3K^+ + PO_4^{-3}

I don't see any "driving force" (no precipitate or weak acid or covalent compound formation) to drive the equilibrium to NaCl + K3PO4.
